How to download rhel 6.4 x86 an x64?

Are you facing any problem? And what version you've want i.e. desktop or server? Just visit Redhat site and check 'How to buy' section (http://www.redhat.com/products/enter...linux/desktop/)

Normally, one doesn't just "download" RHEL; you buy it from Red Hat's website. I don't recall if they offer digital downloads of their install disks (as .iso files).

If you're looking to "download" RHEL (maybe you want to test things out before buying, or don't ever plan on buying), have a look at CentOS, which is quite literally a community-maintained RHEL stripped of Red Hat's branding (along with a few other tweaks, like using CentOS community-maintained updates instead of Red Hat's commercially-maintained updates).

You go to Red Hat's website, and download it. Just a VERY small amount of effort would have told you this, if you tried. And, your question makes no sense....you either can have the software for x86 or x64...not both. Those are two separate downloads.

Try the "Download" button:
https://access.redhat.com/downloads

All you have to do is sign up for a free account, and download what you want. If you're not going to PAY FOR Red Hat Enterprise, you SHOULD NOT USE IT. You CAN use it freely, but you will NOT get fixes/patches/updates, and won't have access to the online repositories. All you will wind up doing is creating a server that's out of date and insecure. Load CentOS instead, which is 99.x% IDENTICAL, but FREE.

Scientific Linux (https://www.scientificlinux.org/) is an alternative to CentOS, both are re-compiled versions of RHEL which are free to use. Scientific may be easier to setup on a desktop or notebook, as it comes with all the multimedia codecs and libraries you need.
